It is beautiful when the Lord brings healing, even when the one who has hurt us has not apologized.
I really like your meter and rhyme scheme, though there are a couple of inconsistencies in the third stanza. Instead of:
"The sticks poke me like knives:"
where sticks and poke are both accented, and there are only six syllables, you might try something like:
The sticks, like knives, elicit cries: or
The sticks are honed to slash like knives:
"Though I pray with all my might."
I think I might drop either "though" or "I", to give it the same meter and syllables you use in the other stanzas. If you remove "I", the reader should make the connection to the one in the previous line. If you remove "though", I would end the previous line with a period.
I hope this is helpful, or at least stimulates possibilities.
